Y liefola'ims.L (ol. 82-34) My invention relates to lathe attachments, and

YSecond to provide means a'daptedtobe` ati tached to arlathe for planing, milling, drilling-and Y otherwiseworking comparatively large pieces of;4

work of the type now worked in yexpensive ma- Y chines designed especiallyV for such operations.

Third, to provide improved means for adapting a standard lathe to perform a Vwide variety .of working. operations. l

Other objects of this invention, ynot `at this time more particularly enumerated, will be'under- I stood from the following detailed description of the same.

WAn illustrative embodiment `disnckzlosirig the im-YAY provements in lathe attachmentsgmade according to this' invention is shown inthe accompanying n drawing, in which:

Fig. .1 is alfragmentary plan view. f7 Fig. 2'is a fragmentary Vvie'win front elevation.

iFig. 3 is a fragmentary View in end elevation. Fig. 4 is a top plan viewrof thelgear carriage."

Y Referring to the drawing, I isV an engine lathe Y provided Vwith a bed 2 having longitudinal ways 3, V3,4ahd a saddle 4. The saddle is of any standard 4construction well known tothose skilled in,V

the art, as are the other parts of the lathe, which therefore require no'further detailed description here.

My novel work holding attachment is mounted near opposite ends of the lathe bed and comprises'a work holder 5 disposed'above and toward the back of the bed. The work holder is in the yform of a solid plate and is provided with T slots' and holes forclamping theworkr in place thereon. The work holder is supported at its oppositerends by means of end plates 6, 6 having f throughan' angleof 90 degrees, permitting three ysideslof the work to be presented tothe tool witharcuate slots .'I nand B-'therein for receiving stud bolts f9 and I0respectively, which are threaded maybetilted about an' upper or a lower horizontalaxisand secured in the desiredtilted position. The ,arcuate slots preferably extend out removal from the work holder. v Y

'ljhe endplates B' are journall'ed at their forward edgeshtothe inwardly egtending ilanges II'and.

l standard cross slide the' scope .jgff usefulness of such machines,

I2 of cross slides I3 and I4, respectively, which are mounted on transverse rails I5, I5. The rails arepreierablyfsecured in place to the lathe bed Ziby means of detachable clamps I6, the arrange-` mentbeingsuchthat the rails may bev quickly' 5 assembled with Aor' detached from'the bed. The cross 4slides I3V and I4 arejmovable relative to eachother andare `secured in'adjusted position'on Y i their rails by` means ofbolts` I'I.v `The journalled connections VI8 between end plates 6 and the @My tool holding attachmenty comprises a powerr driventool holder I9.mounted on the saddle4.

The tool holder is"disposedto rotate about an axis,

arranged in a "horizontal position extending transverselytothe lathebed. "I'he tool holder I9V is carried by a gear carriage 20 which is mounted for vertical movement on. an upright 2|. This upright ispreferably fixed to the cross slide 22 of the saddlelI. The arrangement is such that my cross slide 22 vmay be quickly substituted for they or compound rest ofthe saddle. Y

While the tool holder may be power driven in any desired manner I prefer to drive the tool holder through a belt 23 and a pulley 24. The pulley is connected to the outer end of a pinion v25carryi'ng a worm 26 which meshes with a worm v permitting the carriage l2l] to be moved vertically,

transversely and longitudinally relative vto the Y lathe` ibed. lThus the work clamped tothe work holderv may be readily planed, milled,V bored and the like as desired through the .use of my ,att'acl'iments.V l y "The means 4Iprefer to use forraising and lowering,` the carriage'Zll comprises a hand operated screw'turning'crank 32 disposed above the upp z.

right 2l.. Itis believed that the operation of my attachments. will be apparent to those skilled in tional lathes, ,andv although they are simple and economicalintheir parts, ,they greatly increase`V the art. Theyv are'designed for use with conven-V y lathe bed, vertical end supports journalled to said Icross slides and arranged in spaced parallel rela-- tion above and toward the back of the lathebed a work holder disposed between said end supports, and means connecting said workholde-rv to said end supports so that the-work holder may be turned up or down through an arc of degrees and secured in adjusted position, andthe tool.
